Problems with wireless charging shell

[original.woodster]

Was browsing my phones apps layer today and checked on my battery app and noticed that last night during a charge, the phone was being charged up fully, then depleted rapidly at one point down to 10%, not sure if this has happened previously to me using wireless charging, i took a screenshot and i plan on uploading it later.

Looks like it discharged 3 times to 10% within an hour, could it just be an software issue/bug with Battery app?

Could be an app. For eg. Leaving a torch app running (even with the light off and "behind" the os) will annihilate your battery.
